Hardness Scale
Quartz- A hard white or colorless mineral consisting of silicon dioxide, found widely in igneous, metamorphic, sedimentary rocks.
A
color

streak

is

a

streak

that
determines
what
kind

of

rock

that

it
is
and

what

the
normal
color

of
the
rock

is.
By Emma and Mya and Dakota
Rose Quartz-A translucent pink variety of quartz.
Smoky Quartz-A semiprecious of quartz ranging in color from light grayish-brown to nearly black.
Amethyst Quartz-A violet colored variety of quartz.

More Minerals
Some more minerals are Pyrite, Gypsum, Talc, and Topaz.
Pyrite-Pyrite is a shiny yellow mineral consisting of iron disulfide and typically occurring as intersecting cubic crystals (also known as fools gold).

As you can see can see diamond is the hardest.
The hardness scale is a scale that tells how hard a mineral is. This is the scale.
Igneous Rock is a type of rock that is made by a volcano and it dries over time. It may take over 20 years for a igneous rock to dry or sometimes it drys fast!
It

can

start
out

as
any

of
the

rocks
in

the

cycle.
There
are

three

kinds

of
rocks

Sedimenary,
Metamorphic
,

and

Igneous

rock
This is regular Quartz
The
Rock

Cycle

is

a

cycle
that
happens
to

rocks.

First

a

volcano

explodes
and
the

lava

flows

(Remember this takes years and years)
and
it
rains
and

the

lava

particles

flow
into
the
river

(if there is one near by)
and
it
builds
up
and
goes

to
the

ocean

and
the
it
goes
down

and
the

cycle

starts
all
over

again.
Gypsum-Gypsum is a soft white or gray mineral consisting of hydrate.
Talc-Talc is a white, gray, or pale green soft mineral with a greasy feel.
Topaz-Topaz is a precious stone, typically colorless, yellow, or pale blue, consisting of a fluorine-containing aluminum silicate

Sedimentary rock is a rock that is of or relating to sediment.

A rock that has a sandy feeling.

Definitions :
Weathering is the braking or dissolving up of rocks and minerals on Earths surface.
Erosion is an act of witch earth is worn away, often by wind, water, or ice.
Deposition is the process by which transported materials are left in a new location.
Sediment is any particular matter that can be transported by fluid flow and which eventually is deposited as a layer of solid particles on the bed or bottom of water or other liquid.
Compaction is the process of compacting o the state of being compacted.
Cementation is the act, process, or result of cementing.

What

are
the

3

types
of
rocks
?
Extrusive
igneous

rocks
Extrusive rocks are igneous rocks which form by the crystallization of magma at the surface of the Earth are called extrusive rocks. They are characterized by fine-grained textures because their rapid cooling at or near the surface did not provide enough time for large crystals to grow. Rocks with this fine-grained texture are called Aphanitic rocks. The most common extrusive rock is basalt.
Intrusive

igneous

rocks
Intrusive rocks are igneous rocks which for m by the crystallization of magma at the depth within the earth are called intrusive rocks. Intrusive rocks are characterized by large crystal sizes, i.e., their visual appearance shows individual crystals interlocked together to form the rock mass. The cooling of magma deep in the Earth is typically much slower than the cooling process at the surface, so larger crystals can grow. Rocks with visible crystals of roughly the same size are said to have a phaneritic texture
